Positional parameters in if statement
I am trying to code an if statement that accepts two parameters and see if those parameters are in another file called teledir.txt. If it already exists in the file, it is to say "Entry Exists". If not, I add it to the file and say "Entry Added". This is the code I have so far:
Code:
if [ $# -eq 2 ]; then

                if grep  "$1:$2" teledir.txt; then
                        echo "Entry exists"

                else
                        echo "$1:$2" >> teledir.txt
                        echo "Entry Added"              
                fi

fi


When I run this, if I enter a name and number that is in the file, it says entry added and places it into the file. I'm new to the command line but what am I missing?

www::wikipedia::entry

WWW::Wikipedia::Entry(3pm)				User Contributed Perl Documentation				WWW::Wikipedia::Entry(3pm)

NAME

       WWW::Wikipedia::Entry - A class for representing a Wikipedia Entry

SYNOPSIS

	   my $wiki = WWW::Wikipedia->new();
	   my $entry = $wiki->search( 'Perl' );
	   print $entry->text();

	   my $entry_es = $entry->language( 'es' );
	   print $entry_es->text();

DESCRIPTION

       WWW::Wikipedia::Entry objects are usually created using the search() method on a WWW::Wikipedia object to search for a term. Once you've
       got an entry object you can then extract pieces of information from the entry using the following methods.

METHODS

   new()
       You probably won't use this one, it's the constructor that is called behind the scenes with the correct arguments by
       WWW::Wikipedia::search().

   text()
       The brief text for the entry. This will provide the first paragraph of text; basically everything up to the first heading. Ordinarily this
       will be what you want to use. When there doesn't appear to be summary text you will be returned the fulltext instead.

       If text() returns nothing then you probably are looking at a disambiguation entry, and should use related() to lookup more specific
       entries.

   text_basic()
       The same as "text()", but not run through Text::Autoformat.

   fulltext()
       Returns the full text for the entry, which can be extensive.

   fulltext_basic()
       The same as "fulltext()", but not run through Text::Autoformat.

   title()
       Returns a title of the entry.

   related()
       Returns a list of terms in the wikipedia that are mentioned in the entry text.

   categories()
       Returns a list of categories which the entry is part of. So Perl is part of the Programming languages category.

   headings()
       Returns a list of headings used in the entry.

   raw()
       Returns the raw wikitext for the entry.

   language()
       With no parameters, it will return the current language of the entry. By specifying a two-letter language code, it will return the same
       entry in that language, if available.

   languages()
       Returns an array of two letter language codes denoting the languages in which this entry is available.
